Abstract:
Mosquitoes are generally recognized as the most important vector of many zoonotic pathogens. In this study, seven mosquitoes species were identified ( Anopheles pullus , Anopheles sinensis , Anopheles lesteri , Anopheles kleini , Ochlerotatus dorsalis , Aedes koreicus and Culex inatomii ) in samples collected from Yingkou City, Liaoning Province, Northeastern China. A novel Rickettsia species was detected in Anopheles sinensis (two of 71, 2.82%) and Anopheles pullus (one of 106, 0.94%) mosquitoes. Genetic analysis indicated that the rrs and ompB genes have highest 99.60% and 97.88%–98.14% identities to Rickettsia felis , an emerging human pathogen of global concern mainly harboured by fleas, mosquitoes and booklice. The gltA sequences of these strains have 99.72% of nucleotide similarity with Rickettsia endosymbiont of Medetera jacula . The groEL sequences have 98.37% similarity to both Rickettsia tillamookensis and Rickettsia australis . The htrA sequences have 98.77% similarity to Rickettsia lusitaniae . In the phylogenetic tree based on concatenated nucleotide sequences of rrs , gltA , groEL , ompB and htrA genes, these strains are closely related to R. felis . Herein, we name it ‘ Candidatus Rickettsia yingkouensis’. Its human pathogenicity to humans and animals is still to be determined.
